I wrote some code just over a year ago to write Excel workbooks. At the time the code was tested and functional.

I have since updated to version of XlsIO 6.403.0.15 and when I rerun the code I get the exception message :

'Maximum number of extended formats exceeded'

I cannot find any information on this so would gladly like to know for example howmany formats are allowed and some general info about the above or recommended practice.
